In the Twelfth Night, how does Olivia hope to redress some of the wrongs done to Malvolio?

She will imprison Sir Toby for his offenses.
She doesn't as he is clearly mad.
She will let Malvolio act as plaintiff and judge.
She will give him a raise.

None of the above.

Olivia does not hope to redress the wrongs done to Malvolio. In fact, she is completely unaware of the mistreatment and humiliation he has endured at the hands of Sir Toby, Sir Andrew, and Maria. Olivia only becomes aware of Malvolio's mistreatment and believes him to be mad when he confronts her in a yellow, cross-gartered state. Therefore, she does not believe she needs to redress any wrongs done to him.
